U.S. lawmakers have blasted the White House for its seeming disinterest in the growing immigration crisis on the southern border, with members from both sides of the aisle questioning President Obama's handling of the issue.

But now the Obama administration is apparently pushing back against its critics, warning at least a few Democratic members of Congress to tread lightly, according to Rep. Henry Cuellar, D-Texas.

“A lot of times this administration gets angry when their own party speaks up and speaks out,” Fox News' Brian Kilmeade said Wednesday. “Ask Cory Booker about that. Have you gotten that call?”

“Yes, I have,” Cuellar said. “But let me just say this, I’m not concerned about who gets angry at me at the White House. I’m more concerned about my constituents, who want to find a practical solution to this question that we’re facing down there at the border.”

Since the outbreak of the humanitarian crisis on the border between the U.S. and Mexico, Cuellar has been a fairly vocal critic of the White House’s underwhelming response.

“Who called you?” the Fox and Friends co-host asked. “What, did they tell you to pipe down?”

“We’ll just leave it like that,” Cuellar said. “But notice what I’m doing. I’m still talking about it.”
